Lustrous 1810 Peru 8 reales (Calico-476) graded MS61 by NGC. This coin was minted in Peru after Napoleon overthrew Ferdinand and then kept him as his honored guest in France for 5 years. However, most of Spain did not recognize Napoleon's brother as their new ruler, and the colonies continued to be loyal to Ferdinand. Since no new dies came in from Spain because of the turmoil, the "imagined" busts were created by some mints. Because of the history of the coin and scarcity of the type, they are highly collectible....much more so at the Mint State level.
Coin can be seen on the NGC website, so authenticity of the holder can be verified:
